PRINTING-REGISTER FOR WElGHlNG-SCALES.

SPECIFICATION forming part of Letters Patent No. 616,303, dated December20, 1898.

Application filed April 4, 1898. Serial No. 676,418. (No model.)

To all whom it may concern:

Be it known that we, HENRY FAIRBANKS an d FREDERICK W. TAYLOR,GltiZel1Sof the United States,residing at St; Johnsbury,in the county ofCaledonia and State of Vermont, have invented certain new and usefulImprovements in Printing-Registers forWeighing-Scales, of which thefollowingis a description, reference being had to the accompanyingdrawings and to the letters of reference marked thereon.

Our invention relates to an improvement in printing-registers forweighing-scales, of which a type is shown in the patent granted HenryFairbanks, No. 597,640 and the object of the present invention is toprovide certain advantageous details in the construction of the poise,poise-slides, (he.

The invention consists in the matters hereinafter described and referredto in the appended claims.

In the accompanying drawings,which il1ustrate the invention, Figure 1 isa side elevation, partly in section, of a portion of a printing-beamembodying our invention. Fig. 2 is a section taken at B, Fig. 1. Fig. 3is a section taken at A, Fig. 1; and Fig. 4 is a section taken at C,Fig. 1.

In the drawings the main poise," which by means of rollers o is guidedon the main beam 6, is constructed as shown in the sectional views,preferably with an inclined front wall, as shown at :r. The main poiseis manipulated by the latch (Z in the ordinary way.

Projecting inwardly from the wall :10 of the main poise are integralprojections .2, which are provided with a squared groove, in which isguided the rib y, screwed to the upper edge of the first poise-slide c.This rib y is preferably of a strip of steel and throughout a portion ofits length is provided with notches u to receive the roller upon the endof the springarm 8, which is secured to the upper edge of one of theprojecting pieces One of these projecting pieces .2 is preferablyarranged in a plane directly above the platen, and it fits s ispractically brought over the supporting rollers q, upon which thepoise-slides have an antifriction hearing. The second poiseslide f hasthroughouta portion of itslength an inwardly-projecting part, as shownin Fig. 2, which backs up against the first poise-slide e, and thissecond poise-slide f has also a notched piece 10, upon which bears theroller on the end of the spring-arm s, also secured to one of theprojecting pieces 2. The poise slide 6 is moved through the medium ofthe thumb and finger piece h and the pinion g, engaging teeth on theunder side of said poiseslide, while the second poise-slide f is simi=larly moved by the thumb and finger piece 72/ and the pinion g. Thepoise-slides e and f are grooved on their under sides to snuglyfit theirsupporting-rollers q q.

Having thus described our invention, what we claim as new, and desire tosecure by Let= ters Patent, is

1. In combination with the main beam, a poise slidable thereon, aninwardly-projecting part on said poise, a poise-slide having means forengagement and guidance on the said projection, and means for operatingsaid poise-slide; substantially as described.

2. In combination with the main beam, a poise slidable thereon havinginwardly-extending projections, a guideway formed in said projections,and a poise-slide having a projection in engagement with said guideway 5substantially as described.

3. In combination with the main beam, a poise slidable thereon havinginwardly-er:- tending projections formed with a groove, and apoise-slide provided with a rib engaging said groove; substantially asdescribed.

4. In combination with the main beam, a poise slidable thereon havinginwardly-ex tending projections formed with a groove,

and a poise-slide provided with a rib engagattached to the main poisedirectly above the ing said groove, said rib being also providedprinting-platen. with notches, and a spring-roller supported Intestimony whereof we aiiix our signafrom one of said projectionsengaging said tures in presence of two Witnesses. 11 t 11 u stain -i- 111 s des ri ed.
